Hi Felix, Well on Ubuntu the config used for each installed kernel is found in /boot e.g. /boot/config-`uname -r` But that name or location might be different on other systems. You should grep for VM86, e.g. grep VM86 /boot/config-`uname -r` Depending on which kernel version you are checking the response may be different e.g. on my 3.19 system I get ajb@polly:~$ grep VM86 /boot/config-`uname -r` CONFIG_VM86=y If it's not set then the syscall is not enabled on that system. If it's important to you then please report it as a regression in the distro's bugtracker. e.g. reading a Ubuntu 4.2 32bit config file the response is # CONFIG_VM86 is not set Which is the setting gained from the default value X86_LEGACY_VM86 in Kconfig Thanks On Sun, 4 Oct 2015 04:35:49 -0400 Felix Miata <[email protected]> wrote: > Andrew Bird composed on 2015-10-04 08:16 (UTC+0100): > > > I don't use fedora any more myself, but a quick check online shows that > > Fedora 23 has kernel 4.2.
